Investigation on the mechanical behavior of prestressed glulam bolted joints under combined moment and axial force
Abstract Among the different methods of strengthening glulam bolted joints, the reinforcement method that utilizes steel straps offers the advantages of low cost, convenient installation and satisfactory reinforcing effect. This research presents the results of a series of tests on glulam bolted joints with prestressed steel straps under combined bending moment and axial force, including a theoretical derivation of moment-rotation curves. The findings indicated that the existence of steel straps led to a delay in glulam splitting with a pronounced increase in bearing capacity compared with ordinary glulam bolted joints, i.e. by 46.85 %, 63.17 %, and 53.65 %, respectively. A three-line moment-rotation model was established to predict its mechanical behavior. This research provides valuable insights for the reinforcement of glulam connections under combined load and serves as a reference for future research in this field.
Highlights A novel type of reliable glulam connections was proposed. The proposed joints were tested under moment and axial load. The calculation method of ultimate load and stiffness were derived. Moment-rotation curves could be obtained according to the proposed equations.
